As an 18-year-old college freshman, I am about to become a great-great-great grandmother. To baby fish. A fish tank containing four orange platyfish sits on my desk. One of them, Shasta, is pregnant.

Many of us eat, hear about or see baby fish without ever considering their true adult size. A lot of fish that may seem small and manageable can grow up to be colossal fish that defy our expectations.
